ProWarm TileBacker Pro Insulation Board 20mm

Elevate your underfloor heating and tiling projects with ProWarm BACKER-PRO insulation boards. These premium extruded polystyrene panels, reinforced with fibreglass mesh on both sides, provide exceptional waterproofing and heat insulation, perfectly complementing underfloor heating systems (not suitable for underwood systems). Their superior waterproof surface creates a durable foundation for secure tile fixing, ensuring lasting protection against moisture. With an outstanding thermal conductivity of 0.033 W/mK, these boards significantly boost heating efficiency, reducing heat-up times and energy consumption for enhanced comfort and cost savings.
Available in a range of thicknesses (6mm, 10mm, 12.5mm, 20mm, 30mm, and 50mm), they offer versatility to suit diverse installation needs. Rigorously tested and approved by Instarmac -Ultra, compatibility and reliability are guaranteed. Beyond thermal benefits, these boards also offer excellent sound insulation, creating a quieter living space. Easy to install, they can be cut cleanly with a knife, and are suitable for both floor and wall applications. The boards maintain dimensional stability even in damp conditions.
Installation on concrete subfloors requires Ultra flexible tile adhesive and a suitable primer. For wooden subfloors, use Ultra flexible tile adhesive with ProWarm insulation fixing packs or suitable screws and washers at approximately 300mm centres (around 15 fixings per board). Please note: Polystyrene colour may vary between batches. The boards are not branded 'ProWarm'; the product image is for illustrative purposes only.
